Abstract: 723,420. Chains. FREEMAN (ENGINEERS), Ltd., A., and FREEMAN, A. June 16, 1952 [June 21, 1951], No. 14758/51. Class 24. [Also in Group XXX] A link for a conveyer chain has at least one roller, wheel or equivalent runner to run on a guide track, a longitudinal slot and a headed element adapted to be accommodated in the slot in a next-adjacent link to couple the links in tandem, but with lost motion between them. As shown, Figs. 1 and (not shown) 2, links 1 consist of pieces of rod bent to hairpin shape and having their free ends joined by a short piece of rod 5, welded in position. A head 6 welded on each piece 5 is longer than the gap between the limbs 2, 3 of the hairpins but of less width than this gap, whereby the links can be assembled by inserting the heads into the slots 4 of adjacent links with the links at right angles to each other, and then straightening out the links to form a chain. A cross-rod 8 welded across the limbs of each link has its ends bent at right angles to carry rollers 9 for supporting the chain upon a guide bar 11. A depending bar (not shown) is welded to the rod 8 on certain of the links to support a last carrier constructed as set forth in Specification 723,421, [Group XXX]. Rollers 9 have limited sliding movement on the respective ends of rod 8 to allow of slight twisting of the guide bars 11 which can also be bent in both horizontal and vertical planes. The portions 7 of the limbs to which the cross-rods 8 are welded are cranked. In a modification Fig. 4, crossrod 8 is formed into a C-shape by extensions 15 each carrying three rollers 16, 17, 18 engaging the track 11.

Patent GB-1548764-A (GB)
Title: Photosensitive compositions
IPC: G03F7/021
Filed: 1976-04-12
Abstract: The photosensitive film consists of a coherent first phase of photosensitive material and a second, particulate second phase. The first phase changes its behaviour towards a solvent by exposure with electromagnetic radiation, i.e. it becomes insoluble, and only the unexposed areas can be washed out with the solvent. By using a second, non-coherent phase, up to 75% of the proportion of the first phase can be saved. In this way, the cost can be reduced and the film properties can be controlled by the selection of the chemical properties of the second phase. Thus, films can be activated more rapidly after actinic irradiation than hitherto and the durability of the films when used on offset printing plates was considerably increased. <IMAGE>

Title: Improvements in and relating to knitting machines
IPC: D04B11/00
Filed: 1948-06-05
Abstract: 654,704. Knitting-machines. MELLOR, BROMLEY, & CO., Ltd., and SHORTLAND, A. June 5, 1948, No. 15257. [Class 74 (ii)] A member is driven to-and-fro in a direction parallel to a line of knitting instruments, by mechanism comprising a continuously rotatable cam member bearing two helical tracks of opposite hand smoothly connected at both ends, a follower engaging the tracks and traversed to-and-fro, passing from one track to the other by way of the connecting end portions, as the cam member is rotated and controllable means for causing the follower to remain at an end of the rotating tracks as required, the follower being connected to, or arranged to be connected to, the member to be driven to-and-fro. Followers 9, 10, 11, connected to main yarn carrier rods 44, plating yarn carrier rods 45 and slurcock member 21, traverse along helices 5, 6 of opposite hand, formed in or on a rotating drum 1 and united at their ends by parts 7, 71 which provide sufficient dwell for the performance of operations such as dividing, loop forming and knocking-over. Each track may have an intermediate part of constant pitch, merging into the parts 7, 71, by portions of progressively varying pitch, the followers being rotatable about axes 22, 23, 24, normal to the drum surface. At the ends of the tracks the followers may be diverted into and from idle tracks (made up of the parts 7, 71 and other parts 15, 151) by switch cams 16, 16<SP>1</SP>, displaceable axially or radially for this purpose. As shown, the switch cams are moved by ramps 31, 31<SP>1</SP>, on a bar 29 connected to a slidable sleeve 33 bearing a helical track in which engages a follower 38 on a rotatable cuff 39. The cuff is rotated through connections 41 from a bolt 58 which is moved by a spring 60 when a detent 57 is disengaged by a stud on the main pattern chain 52. If, in addition, the pattern chain disengages a detent 67, a roller 62 is also pressed by a spring 63 into the path of shogging cams, to shog the cam-shaft 49. The bolt 58 is forced out, as the cam-shaft rotates, by a re-setting cam 61 and, if the stud layout of chain 52 is such that detent 57 or detent 67 is re-engaged, the cam-shaft 49 shogs back to its original position. According to the Provisional Specification, the control means for causing a follower to stand still may comprise means for effecting disengagement between the follower and an end portion of the tracks. The arrangement may move a needleoperating carriage or lock. Specification 638,872 is referred to.
Patent GB-501838-A (GB)
Title: Improvements in and relating to coupling devices for electric circuits
IPC: H03F1/50
Filed: 1937-06-02
Abstract: 501,838. Impedance networks ; transformers. BRITISH THOMSON-HOUSTON CO., Ltd. June 2, 1937, No. 15341. Void. Convention date, June 2, 1936. [Class 40 (iii)] [Also in Group XXXV] The Specification describes a coupling suitable for use in a valve amplifier for television and having a uniform transmission characteristic over a wide range. The coupling comprises a transformer whose primary and secondary windings are divided into similarly tuned parts and are provided with shunt resistances. Resonances arising from the capacity inherent in the coils are distributed over the frequency range by dividing each winding into sections which are resonant at different frequencies and are magnetically discoupled from one another so that each section provides a channel for part of the frequency range. Resonances between the inductive reactance of one section and the capacitive reactance of another, at frequencies intermediate between the resonance frequencies of the sections, is avoided by shunting the higher frequency section with a resistance equal to the inductive reactance of that section at the frequency in question. In simple cases, the primary and secondary winding may each be divided (1) into two sections, one of which is shunted by a resistance, Figs. 1 to 3 (not shown) ; or (2) into three sections, those corresponding to medium and high frequencies being shunted by resistances, Fig. 4 (not shown). If the windings are mounted on one core as shown in Figs. 5, 6 (in which the channel of lowest frequency is provided by the windings 28, 31 while channels of successively higher frequencies are provided by the remaining windings), those windings which gerve different regions of the frequency range have to be magnetically discoupled in order that the capacitive reactance of one winding may not effectively load the other windings. The discoupling of the winding-sections allocated to different frequencies is completed by the insertion of condensers 36, 38, the windings being connected partly in series and partly in parallel. The Specification describes two-terminal circuits, Figs. 7 to 13 (not shown), equivalent to the input aspect of the coupling system at various ranges of frequency, and indicates how the voltage across the load, represented by a resistance 3<1>, can be maintained throughout the frequency range. In order that the distributed capacity of the winding 28 may not overload the source at high frequencies, additional primary coils shunted by a resistance may be wound on the outer legs of the core 27, Figs. 14, 15 (not shown).

Title: Improvements in and relating to the determination of distances by means of reflectedsound waves
IPC: G01S7/526
Filed: 1922-02-04
Abstract: 200,464. Baron, H., (Signal Ges.). Feb. 4, 1922. Determining distances acoustically.-Relates 'to the method of depth sounding in which a sound is delayed so as to be heard simultaneously with its echo, and comprises the provision of a sound-operated switch for preventing the listener from hearing the original sound at the instant when it is first emitted. The. sound of an explosion 8, Fig. 1; on reaching the detector 2 makes a record on the telegraphone 6 which after a measured interval affects the receiver 5, and at the same time, by decreasing the current through the relay 7, it closes at 10 the circuit of the detector 2<1> ready for the echo which will be heard at 5<1>. The receiver 5<1> is however unaffected by the direct sound of the explosion which occurs when the contacts 10 are open. In the form shown in Fig. 2, the echo reaches the earpiece 5<111> through a, tube 14<1> from the telephone receiver 5<1>, which is however cut off at the switch 3 when the explosion takes place. The initial sound acting on the detector 2 causes the armature 9 to be released, closing the circuit of the magnet 18 which operates the switch 3 and puts the receiver 5<111> in circuit ready for the echo. The initial sound acting on the receiver 5 through the microphone 2 and transformer 12 starts a disturbance which travels along the trombone tube 16, is weakened by a damping device 17, and reaches the earpiece 5<11> after an interval which is regulated by adjusting the trombone tube until the disturbance is heard simultaneously with its echo. An additional detector 2<1> may be used to operate only the switching relay. Simultaneity of the sounds in the earpieces 5<11>, 5<111>, may be tested by the binaural method or by optical methods. Specification 189,807 is referred to.
